In late M41, the Tombs of the Necrons buried deep within the world activated, causing the ancient constructs to rise up and wreak destruction. The Imperium responded by sending a force of Attilan Rough Riders under Mogul Kamir, resulting in a grueling three year war. In the end, the Necrons were finally defeated during the ill-fated charge of Lumen Valley, the largest cavalry charge in the Imperium's history.[1a]

As thanks, Loxar IV's Tech-Priests presented Kamir with a cybernetichorse. Kamir, who had become used to his steeds collapsing under him from wounds or exhaustion, could not have been more appreciative.[1b]
